Semer was fleeing a traffic stop Saturday night in the area of North 19th Street about 11:55 p.m., police said.

Semer played parts of three seasons with Fort Pierce Central High School's varsity football team. A backup quarterback and wide receiver, he completed 15 of 29 passes for 219 yards and two touchdowns and caught nine passes for 82 yards and a touchdown.

Semer signed with Elmhurst College in Illinois as a quarterback in 2013, but never played a game for the Bluejays. He returned to Fort Pierce in 2014.

Saturday night, Semer is accused of running over one of the officers, injuring his leg, as a second officer was getting in Semer's vehicle.

The second officer couldn't get out of the moving car and fatally shot Semer before the car stopped about 600 feet farther in a residential area on North 19th Street near Avenue G, according to a sheriff's news release.

Semer was pronounced dead at the scene. The injured officer was treated at Lawnwood Regional Medical Center & Heart Institute and released.
